The ucspilogd program

ucspilogd reads a stream of syslog-like messages on stdin, converts syslog facility numbers and alert levels into names, and prints the result to stdout.

Interface

     ucspilogd

Common use

You can emulate the whole syslogd behaviour by combining the following components:

• A Unix stream super-server such as ipcserver, listening to the Unix domain socket /dev/log, to connect to the kernel log-reading interface.
• ucspilogd running under that super-server, to read the logs and perform adequate transformations.
• A logger such as multilog or svlogd, to store the logs into the filesystem.
• A supervision mechanism such as daemontools or runit, to ensure ease of use and reliability of the whole chain.

The resulting suite of programs is still smaller, and way more reliable, than a standard syslogd.

In the service subdirectory of the ucspilogd package, you will find a suitable ucspilogd service directory usable with daemontools or runit. The run scripts are written in the execline language.

Using ucspilogd as a klogd replacement

Certain Unix kernels offer a nice interface to the kernel logs. For instance, the Linux kernel provides the /proc/kmsg fake file, that can be opened and read like a normal file, excepts that it gives the kernel logs when they are available and blocks otherwise. You can use ucspilogd to process data from those interfaces.

The service/klogd-linux subdirectory of the ucspilogd package is a service directory providing such a klogd service for Linux, using the /proc/kmsg interface.
